The etiology of constriction band syndrome is incompletely understood, but the leading theory suggests that partial rupture of the inner amnion prior to fusion with the outer chorion creates fibrous chorionic bands that constrict fetal parts. Given the heterogeneity of malformations, a comprehensive physical examination is essential for accurate diagnosis. Depending on the severity of the constriction band, surgical intervention can range from simple excision of constriction bands to on-top-plasties in cases of digit deficiencies. Importantly, each patient should receive an individualized approach based on their anatomy, which considers the urgency of constriction band release, preservation of the neurovascular structures, viability of the distal body part, and maximization of functionality. With these goals in mind, surgical management of constriction band syndrome regardless of presentation can greatly improve function and cosmesis in affected children.</p>","PeriodicalId":48687,"journal":{"name":"Seminars in Plastic Surgery","volume":"40 3","pages":"253-260"},"PeriodicalIF":1.4,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13485369/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148799896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article reviews three distinct congenital and acquired thumb deformities: pediatric trigger thumb, triphalangeal thumb, and congenital clasped thumb. Pediatric trigger thumb, an acquired condition resulting from a size mismatch between the flexor pollicis longus tendon and the A1 pulley, is staged using the Sugimoto classification and can resolve spontaneously, though surgical release of the A1 pulley reliably restores full range of motion in refractory cases. Triphalangeal thumb presents across a wide spectrum from a single extra phalanx to a five-fingered hand with absent thenar musculature and is classified by the morphology of the extra phalanx to guide surgical reconstruction. Congenital clasped thumb, a flexion-adduction deformity caused by hypoplasia or absence of the thumb extensors, can be categorized by either Tsuyuguchi's system or Mih's modification of McCarroll's system and managed initially with splinting. Surgical reconstruction is reserved for resistant or complex cases.

Established principles of reconstruction dictate a staged approach to address the primary components of the deformity: radial wrist deviation and/or thumb deficiency. Severe RLD remains one of the most challenging conditions to manage, and no technique has yet achieved reliably durable correction. The goals of surgery are to create a stable carpal platform, achieve tension-free correction of soft tissue contractures, and restore a functional pinch mechanism. Surgical options for wrist stabilization may include soft tissue rearrangement and tendon transfer, centralization, free fibula flap, and radialization/ulnarization. Recently, adjunctive techniques such as soft tissue distraction and ulnar cuff osteotomy have been employed to facilitate correction and may benefit ulnar growth. Special considerations are described for thumb hypoplasia and limb length discrepancy. Outcomes are generally favorable for functional use, although long-term objective results remain suboptimal relative to normal function, and recurrence of angular deformity remains a significant challenge, underscoring the need for continued research.
